WILLIAM H. GRAY, OF WEST FALLS, MARYLAND.

SHlNGLE-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 278,128, dated May 22, 1883,

Application filed February 13, 1883.

To all whom it may concern:

Be it known that I, WILLIAM H. GRAY, a citizen of the United States, residing at West Falls, in the county of Frederick and State of Maryland, have invented certain new and useful Improvements in Shingle Machines, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to certain new and useful improvements in shingle machines, and more particularly to a machine that can be readily adjusted to ordinary circular or bandsaw machines by placing the shingle machine on the bed or tables of said sawmachines, with but little or no change in its construction. 1

The object of my invention is to produce a shingle-machine that can be readily operated by a single attendant, that will first prepare the block or shingle-bolt for use in proper form, and then by cutting the shingles from heel to point alternately use the block entire without waste, and deliver the perfectly-formed shingles on the out or rear side of the sawframc, ready for bunching.

Another object of my invention is to utilize twisted or knotty material that would for other purposes be useless.

I attain these objects by means of the mechanism hereinafter more fullypointed out in the specification and claims.

Referring to the drawings, Figure l is a perspective view of myimproved shin gle-machine,.

showing the machine attached to the table of a sawing-machine. Fig. 2 is a top plan view of the same, showing the gage-frame retracted after a shingle is out from the bolt. Fig. 3 is a longitudinal sectional view through the center. Fig. 4 is a sectional end view, showing the trip-lever and inclined stud for lifting the same. Fig. 5 is a plan view of the bed or table of a circular saw machine with cross-sills, spring, guide-strip, and operating-stud attached. Fig. 6 is a detail view of the shingle remover or cleaner. Figs. 7 and S are detail views of the gage, pawl, operating-lever, and stud.

Similar letters refer to similar parts throughout the drawings. i

In the drawings, A refers to a saw bed or (No model.)

table, upon" which are secured two or more (preferably three) strips or sills, a, at the proper distance apart and in line with the movement of the saw.- Upon said strips or sills the frame B rides in its movement forward and back across the bed or table A, in line with the saw, as each shingle is cut. Frame B is formed with strips 1) and I), having projecting lips on theirlower faces to register with projecting lips formed on the bed strips, or sills a. Said strips b are joined together and held in proper place as follows: A wide cross-piece, b, extends across the upper face of strips 11 and b near their front edge, and to which strips 1) are attached. On the upper face of strip b, anda short distance from its front edge, is secured a hand -rest or grip-piece, b, by which said frame is moved to and from the saw.

. Short strips 0 and 0, attached at their ends to strips 1), form the bed on which the shingle bolt or block is laid while being out into shingles. An arm-piece, c, is secured to c, that extends outward and engages with springcatch 0, formed to limit the movement of the frame, when retracted, after the saw has passed through the bolt. To the center of arm 0 is attached one end of rope e, that passes under the frame and over a pulley down through an aperture in the saw bed or table, and is atof strip 1), the purpose of which is to permit the shingle-bolt to be laterally adjusted to conform to the adjustment of the gage, as shown in Fig. l. A flexible spring, f, is attached at its inner end to the upper face of strip 1), as shown in Fig. 2. The outer end of said spring engages with a pin, f, projecting. the center of cross-bar 7", the purpose of which is to retract a portion of the frame carryingan adjustable guide, 9. Said guide is pivoted at its center to a strip, 9, extending outward to the cross-barf. The outer ends of cross-bar f are secured to side bars, 9 and that extend inward parallel with strip 9 to near the inclined outer edge of guide g. The inner ends of side bars,'g and g, are cut inclined to conform to the inclined edge of guide Across the upper faces and rear ends of strips 1) is secured a wide cross-bar, h, to which is at- IGO tached one end of rope h, that passes over a pulleyjournaled in bed A, near its front edge. The outer end of said rope is attached to a weight, 0, below bed A. v

On top of frame B, and near the end, is secured an upright cross-piece, 6, attached by its ends to cross-bar h and strip I). Said crosspiece is formed with tapering ends, and recesses 1 l and 2, cut in from its under edge. On its rear end and inner face is pivoted a pawl, 'i. The outer end of said pawl is formed with a short incline on its under edge, that comes in contact (when the frame B is pushed to the rear) with stud i, secured in line with said pawl to the rear end of bed A, by means of which said pawl is operated, and against which frame B abuts when pressed rearward far enough to permit the saw to traverse the length of the shingle-bolt. A similar crosspiece,-j, is attached in like manner to crossbar h and strip b at a point near the inner end of cross-bar h. Said cross-piece is recessed on its under edge for the reception of side liars, g g, and center strip, g. A portion of the inner ends of side bars, g g, extend inward ashort distance beyond theinner edge of guide g, and are rigidly secured to a bed-strip, j, on which the lower edge of the shingle rests when the saw is passing through the block or bolt. On the upper face and front endof guide 9 one end of a flexible rod, j, is attached. Said rod extends along the upper face of side bar 9', passing a recess in cross-piece j. The outer end of said bar or rod has projecting from its upper face a hand-pin, k. 011 its front face are secured two projecting lugs, 7c it", formed to engage with a projecting lug, Z, attached to side bar g and projecting upward between lugs 7c On the upper face of center strip, 9, near cross-bar j, is located a hand-pin, 1, secured in place for the purpose of moving said strip to or from the saw 0. Between said hand-pin and cross-pieced is attached a pointed projection, I, that acts as a fulcrum for a notched pawl, I. Said pawl is held loosely on the point of said projection by a screw-bolt or other suitable device. Pawl I has a hand-pin, l, projecting from its upperface and innerend. The outer end of said pawl is shouldered to engage with the inner edge of recess 2, as shown in Fig. 3. A modified form of this part of my device is shown in Fig. 7, in which the pawl l" is shown plain,andhingedatitsinnerendtohandpin Z, the outer end of said pawl being recessed on its under face to engage with the top of cross-piece above said recess, and on the upper face of said pawl a hook, 922, is secured, said hook being formed to engage with the inner end of lever m, pivoted on crosspiece 1 The outer end of said lever isformed tapering on its upper face to engage with stud on", having an inclined recess on its inner edge. The purpose of this construction is to lift the end of pawl I, when the frame is forced rearward, by the end of lever an entering the inclined recess in stud m.

snares Parallel with center strip, g, extends a shingle-rest, a, passing through a recess on the upper face of cross-piece j and above guide 9.

The lower half of said rest forms ashingleremoverm. Near the inner end of rest it pro-. jects a pin, a". The lower half or shingle-remover extends outward to the end of the frame B, its upper face having a fulcrum,p, on which is pivoted a pawl,o",having ashouldered recess, 1), and hand-pin o, as shown in Fig. 6. v

Secured between the two standards I) to the table or bed in an oblique position is a guide-strip, y, against which pin 3 moves, and by which the sliding cross-frame D is operated.

Near the front and outer edge of saw-bed A is secured a spring-catch or stud, r, to prevent the frame from being drawn off the table.

The operation is as follows: The frame B is placed on the sills of the table. frame D is drawn back with the rest at. A rough bolt or block from which the slabs are to he cut is placed on the frame outside of the saw. The frame is then pushed rearward until the saw passes through the bolt, cuts off the slabs, and leaves it in condition for cutting shingles. The frame D is then moved inward until the pawl Z engages with the cross-piece 2'. The rest a is also moved in ward until its inner end is in line with the inner face of guide 9. Guide g is set to cut a shingle thick at the rear end and thin at the front, as shown in Fig. 2. Also,the guideand operating-lever are shown set in Fig. 1. The block is then passed rearward on frame B until the saw cuts a shingle from its inner face, when the frame is drawn back to the front, the guide set to out the rear end of the shingle thin and the front end thick. This operation is continued until the bolt or block is used up.

Having described my invention, what I desire to secure by Letters Patent is 1. The frame D, having side strips, g" and 9, extending to the strip j, the shingle-guide g, pivoted to center-piece, g, the shingle-remover n, carrying pawl 0", in combination with cross-bars i and j, pawl i, and stud i, the frame B, and spring f, substantially as shown and specified.
